11
how to label specimen
last name, first name, MI
specimen or patient no.
12
when to label specimen
after collection/filling up the tube
13
number 1 reason of specimen rejection

15
inside cell what ions are abundant (and their ratios)
K (20:1)
Mg (10:1)
16
hemolysis of RBC leads to
false elevation of analyte concentration
17
straw colored yellow fluid
serum
18

room temp
21
reasons of rejection
questionable labelling
hemolysis
QNS
22
Substance added to blood to prevent clotting
Anticoagulant
23
mechanism of action of anticoagulant
1) can precipitate, bind, complex Ca thus Ca is removed
2) by acting as antithrombin
24
stages of clotting process
generation of thromboplastin
conversion of prothrombin to thrombin
conversion of fibrinogen to fibrin clot
25
Ca dependent stage of clotting process
generation of thromboplastin
26
Thromboplastin dependent stage of clotting process
conversion of prothrombin to thrombin
27
thrombin dependent stage of clotting process
conversion of fibrinogen to fibrin clot
